Q: In which application is hydrogen used as a reducing agent?
Solution: Hydrogen acts as a reducing agent in the extraction of metals from their ores, such as in the reduction of metal oxides.
Steps: 6
Step 1: Understand what a reducing agent is. A reducing agent is a substance that donates electrons to another substance, causing the other substance to be reduced.
Step 2: Learn about hydrogen. Hydrogen is a simple element that can easily donate electrons.
Step 3: Know that metals are often found in nature as metal oxides (compounds of metals and oxygen).
Step 4: Recognize that to extract pure metals from their ores, we need to remove the oxygen from these metal oxides.
Step 5: Understand that hydrogen can react with metal oxides to remove the oxygen, thus reducing the metal oxide to pure metal.
Step 6: Conclude that hydrogen is used as a reducing agent in the extraction of metals from their ores.
